This laptop uses UEFI. By default secure boot is enabled. Though is should be possible to set up a secure boot loader ([Secure Boot](/index.php/Secure_Boot "Secure Boot")), I chose to simple turn off secure boot. Also, though the laptop does support booting from legacy devices I discovered that this causes serious video issues (you can not boot into the CLI with KMS enabled but disabling KMS prevents X from starting). Simply turning off the legacy boot option fixes this issue.
### Entering Setup
This laptop hides the "Push XXX to enter setup" message during boot.
1. Power on the laptop
2. When the Dell logo appears, press ESC
1. If timed right, two lines of text will appear in the lower right corner of the screen
3. Press F2 to enter setup
### Disabling Secure Boot
As mentioned above, disabling Secure Boot permanently may not be necessary but I was unable to find a way to boot the Arch install image without doing so.
Once in setup:
1. Go to the "Boot" tab
2. Disable "Secure Boot"
### Disabling Load Legacy Option Rom
With this option enabled the laptop screen would shut off while booting the install media and when booting the installed system unless KMS was disabled. Disabling KMS, however, prevents X from starting as, from what I have read, the xf86-video-intel driver requires KMS.
Once in setup:
1. Go to the "Boot" tab
2. Disable "Load Legacy Option Rom"
## Base Install
Once setup has been configured, installation using the [Installation guide](/index.php/Installation_guide "Installation guide") and [General recommendations](/index.php/General_recommendations "General recommendations") proceeded without issue. As this laptop uses an Intel processor, pay attention to the sections covering microcode updates.
## Configuration
### Video
#### Drivers
[xf86-video-intel](https://www.archlinux.org/packages/?name=xf86-video-intel) works without issue.
#### Brightness
The brightness hotkeys (Fn-F11 & Fn-F12) did not work for me out of the box but they will if you are using a full desktop environment like Gnome or KDE. Still, I had no trouble making the hotkeys work using information found on the [Backlight](/index.php/Backlight "Backlight") and [Extra keyboard keys](/index.php/Extra_keyboard_keys "Extra keyboard keys") pages and my window manager's documentation. My solution involved configuring my window manager to map the XF86MonBrightnessUp and XF86MonBrightnessDown keys to run the appropriate xbacklight command.
### Wireless
Wireless worked with no additional effort on my part. This is fairly important as this model does not include a wired port.
### Audio
Audio using [ALSA](/index.php/ALSA "ALSA") worked immediately after install.
If no sound is coming from the headphone jack, try adding
`options snd-hda-intel model=dell-headset-multi`
to `/etc/modprobe.d/snd-hda-intel.conf`
Most of the extra keys did not work for me after install. Some or all will work if you use a full desktop environment like Gnome or KDE though. I was able to configure my window manager to run appropriate commands when the extra keys are pressed. The Enable/Disable wireless key did work without any extra work on my part. However, the page up and page down keys (activated by pressing Fn + PageUp or PageDn) do not work as expected. After pressing and releasing them, the scrolling action will be glitched and will not stop. To fix this create the following [hwdb](/index.php/Map_scancodes_to_keycodes#Using_udev "Map scancodes to keycodes"):
`/etc/udev/hwdb.d/90-custom-keyboard.hwdb`
```
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnDell*:pnInspiron*3162:pvr*
KEYBOARD_KEY_c7=!home
KEYBOARD_KEY_cf=!end
KEYBOARD_KEY_c9=!pageup
KEYBOARD_KEY_d1=!pagedown
```
Pay attention to formatting. This is the first reason why it may not work.
When I first installed xorg, I installed [xf86-input-evdev](https://www.archlinux.org/packages/?name=xf86-input-evdev) as the only input driver. This caused the touchpad to react like a disembodied touchscreen. I then replaced [xf86-input-evdev](https://www.archlinux.org/packages/?name=xf86-input-evdev) with [xf86-input-libinput](https://www.archlinux.org/packages/?name=xf86-input-libinput) this caused the touchpad to work fine but the keyboard stopped working once I started X. With both [xf86-input-evdev](https://www.archlinux.org/packages/?name=xf86-input-evdev) and [xf86-input-libinput](https://www.archlinux.org/packages/?name=xf86-input-libinput) installed, the keyboard and touchpad both work fine.
If your touchpad stops working after suspend, it might be due to a [problem with the i8042 module](https://bbs.archlinux.org/viewtopic.php?pid=1550691#p1550691).
To make taps work as clicks on the touchpad this file has to be created (see [libinput](/index.php/Libinput "Libinput")):
`/etc/X11/xorg.conf.d/30-touchpad.conf`
```
Section "InputClass"
Identifier "touchpad"
Driver "libinput"
MatchIsTouchpad "on"
Option "Tapping" "on"
EndSection
```
### Camera
The camera worked without effort on my part. I tested by installing running guvcview.
### Card Reader
It works as expected.
### Bluetooth
The bluetooth hardware is recognized and the appropriate modules are loaded. I am also able to turn on power and detect other bluetooth devices. Pairing works, and so does file transfer from and to the device.
### Suspend & Hibernate
Suspend and hibernation do work fine with no extra work on my part.
